I haven't heard anything one way or the other. But it seems clear that the Mac Pros are overdue for an upgrade and there weren't any suitable processors to upgrade to until Monday's announcement by Intel.
There was talk that supply issues might be the current constraint, so I do think it's an any-day now sort of situation. I'm not sure if they'll bother waiting until MWSF, since it sounds like there are other plans in the works for that event (thin macbook rumors etc...)

Thanks for your insight. Hopefully Apple pulls through and surprises us all this month. I'll do my best to hang on as long as I can.
